Once you have selected the providers, first I suggest you personally visit each site and look for the features they offer. If the functions are adjusted to your requirements, then you can talk with one of your agents, and at the same time clarify your doubts, make sure the agent is friendly, since once you start using your service, you should talk to them regularly to get details and assistance. The agents must be helpful and friendly. If the provider does not have a chat facility, send a ticket and check the response time, the sooner it is good.
Once you have clarified these points, you can verify if your chosen provider offers any test facility. Usually, providers do not offer a test, but there are some providers that offer a test for a lower price. You can subscribe to a lower price test service. If you are satisfied and satisfied, you can continue with your service.
I hope these help you to be a good provider.
